I guess the way I see it is that the situation in Iraq doesn't seem to be changing at all. We're 4 years in and there's hardly any change from the time we first went in. The only difference is that the bad guys are getting smarter about how to run an insurgency.
Is the situation getting any better? If the answer is no, then how will more troops there make a difference? Seriously. Do they patrol more? Search more houses? Basically act as police? Without a change in tactics will we see any improvement?
As I've stated since 2003 and earlier, the long term goal of going into Afgh. and Iraq IMHO is to create platforms to launch an eventual invasion of Iran. I don't think the US would be dumb enough to start it at this point, we are just waiting for Iran to instigate a war (which is looking more likely on a daily basis) that way we can get the UN truly behind our backs. Really, if Irans' govt. is changed I would bet you that Iraq will quiet down tremendously.
